All, Is it possible to backup/restore the memory management settings do you know? When you enable the memory management optimisation in 4/4.5 etc a log is created of the apps loaded, from which the memory optimisation takes place at an appropriate interval. If you rebuild a machine this is effectively 'lost' - would simply backing up and restoring the files, then forcing an update on reboot work... does anyone know/have experience of? And finally - if I did want to script that "force an update" bit, anyone know how? Save me some work tomorrow and of course, if I ever see you, the beer is on me. Ta muchly...
